Ryzen 5000 Series Ready

The MEG B550 UNIFY-X motherboard supports AMD Ryzen 5000, 4000 G-Series & 3000* Series (not compatible with Ryzen 5 3400G & Ryzen 3 3200G).

• Form Factor: ATX
• Socket Type: AMD AM4
• Chipset: AMD B550

Unleash Maximum Power

An aggressive VRM design employs dual 8-pin power connectors, direct 14+2 digital power phases, a mighty 90A power stage design, and Titanium Choke III inductors.

Augmented with MSI's Core Boost technology, the MEG B550 UNIFY motherboard is ready to push high-end CPU's to their extreme limits.

Passive Cooling

VRM Cooling: Features dual thermal dissipation pads (7 W/mK), dual aluminium heatsinks (with interconnecting heat pipe) and MOSFET thermal backplate.

PCB Cooling: Premium 6-layer printed circuit design with 2 oz. thickened copper improves heat dissipation & reliability.

Chipset Cooling: Enlarged chipset heatsink & M.2 Shield Frozr (double-sided).

Fortified PCI-e 4.0 x16

MSI PCI Express Steel Armor slots are secured to the motherboard with extra solder points to support the weight of heavy graphics cards. When every advantage in games counts, Steel Armor also shields the point of contact from electromagnetic interference:

• 1 x PCI-e 4.0/3.0 x16 slot (with Steel Armor)
• 1 x PCI-e 3.0 x16 slot (CrossFire supported)
• 2 x PCI-e 3.0 x1 slots

Quad M.2 Connectors

The MEG B550 UNIFY-X motherboard features MSI's latest Lightning Gen 4 M.2 ports which represent the fastest onboard storage solution available with up to 64 Gb/s transfer speeds (3 x PCI-e 4.0, 1 x PCI-e 3.0).*

*M.2 specifications may vary depending on the CPU installed.

Double-Sided M.2 Shield Frozr

Even the world’s fastest SSDs will automatically slow if thermal throttling firmware detects excessively high temperatures.

Double-sided M.2 Shield Frozr is MSI's most advanced thermal solution, offering the best possible protection to ensure maximum SSD transfer speed performance.

Extreme RAM Overclocking (5800MHz)

DDR 4 Boost: A fully-isolated DDR circuit delivers pure data signals for optimal gaming and overclocking performance.

A-XMP profiles in MSI BIOS are MSI OC LAB tested and can be easily enabled with auto power settings for optimized memory speed and stability.

Excellent Connectivity

2.5Gb/s LAN: RTL8125B-CG 2.5Gb/s LAN with LAN manager, delivers a premium network gaming experience.

Wi-Fi 6: The latest wireless solution supports MU-MIMO and BSS color technology; Bluetooth 5.1 supported.

HD Audio: 7.1-Channel High Definition Audio with Audio Boost 4 & S/PDIF output.
